having a side wall 50; a top wall 5|, and a depending hollow hub portion 52. The latter is keyed internally at 53 with the upper end of the vertical shaft section 33. Ihe drum 50 at its lower end is provided with an inturned wall defining a water receiving compartment 30.

A catch basin for receiving drain water is attached to the plate 30. It includes a bottom wall centrally provided with an upstanding cylindrical-shaped wall SI which extends into the drum 50; terminating at its upper end just short of the lower surface of the top wall II of the drum, and of course spaced from the inner wall of the drum which defines the compartment 50, as shown in Figure 4. Suitable upstanding outer walls 13 are provided to define a compartment 15 adapted to receive water. A lateral extension 11 may be provided at the rear of the machine; the compartment 15 being extended thereinto. This portion 11 extends beyond the outer surface 'of the rear wall I2 of the casing C, and is provided with a depending drain conduit 30, the lower .end of which is positioned above the drain water receiving cup SI of a con duit 02. The wall 50 of the catch basin is bolted, as at 03, to the unit plate 30, as shown in Figure 4.

The units B each include a central spindle I00 axially aligning with the drive shaft or spindle 33, screw threaded upon a supporting plate IOI which is attached or bolted, as at I02, upon the top plate 5| of the drum E. Auxiliary supporting posts I05 are mounted upon the top of drum 50. At their upper ends the supporting posts I05 and the central spindle I00 detachably support a guide plate IIO; nuts III being provided upon the upper end of the spindle I00 to hold the plate H0 in position. As is usual, an annular groove is provided in this plate I05 to rotatably support a ring-shaped member I I2 having a guide eye I I3, for a purpose well known to those skilled in this art.

' As is shown in the drawings, the units B are mounted in line with the shafts 4| of the units in axial alignment. The ends of these shafts are bonnected together by means of flexible coupling s 420. The motor G of course has a shaft I2I which is detachably connected with the shaft ll of the end unit B by means of a similar flexible coupling I20.

An improved oil system is provided for the machine consisting of an oil pump I30, shown in Figures 2 and 3 of the drawings, mounted upon the end wall I8 of the casing C. This oil pump is provided with a supplyline I3I and an outlet line. I32 which leads lengthwise of the machine within the compartment 20 of the casing or body portion C. For each unit the conduit I32 is provided wtih a branch conduit I40 having a detachable coupling connection I with a short conduit I02. The latter is. provided as a part of each unit B detachably connected upon the depending sleeve portion 33", as shown in Figure 6 of the drawings and provided .with suitable duct passageways I leading to the anti-friction bearings 35, and to bearings 36 not shown in Fig. 6.

The rear wall I2 01' the casing C is provided with handholes I50, normally covered as at I5I, and thru which access may be had to the flexible drive shaft couplings I20 and the oil pipe couplings I, when it is desired to detach the units at the'secouplings and connections for removal of the unit or units from the single piece casing C. It should be noted that there are no lateral extensions upon any of the units, after detachdrawings.

ment of these couplings and connections, which would interfere with the complete detachment of any unit without disturbing an adjacent unit.

The motor G is provided with a switch mechanism I60 controlled by operating mechanism ,I3I running along the length at the front of the machine.

While in the preferred instance I use individual overhead pulleys for the units, I may provide a single transfer. roller for the machine. The latter consists 01' a horizontally positioned overhead roller I65, supported upon uprights or standards I06 and I61 adjacent the ends of the machine, and over which the wire is trained for transferring from one unit to the next unit.

For each unit B there is provided a soap box and die holder construction. The soap box is designated at I10 in Figure 9 of-the drawings. It is pivoted at I1I upon upstanding brackets of a supporting plate I12. This horizontal pivot I1I provides for vertical adjustment of the soap box. Regulation of the vertical adjustment is had by means of thumb nuts I13 threaded upon a screw threaded shank I14. The latter is attached to the base I12 and extends loosely thru an opening in a lateral projection I15 provided integral upon the soap box I10, as shown in the drawings.-

The base I12-is pivotally mounted upon a vertically positioned pivot bolt I13, detachably connectedupon the rail flange of the front wall II of the casing C. The soap box may be adjusted laterally upon this pivot I13 by means of an' L-shaped screw threaded member I00 which is loosely hooked in an eye IlI upon the casing C, at one end, as shown in Figure 4 of the drawings. At its screw threaded end it extends thru an opening in a depending portion I82 of the base portion I12 of the soap box-die holder. Wing nuts I84 are screw threaded upon this member I at each side of the depending portion I02.

The soap box is provided with die holder portion I providing a socket IOI for receiving a die casing. The base portion I12 is provided with a flange or stop portion I03 extending across the die casing socket IOI, as shown in Figure 9 of the drawings, to act as a stop for the die casing. This stop may have an adjustable stop screw I mounted thereon. A die casing clamping screw I90 may also be provided upon the soap box-die holder, as shown in Figure 9 of the drawings.

The stringing of the wire upon the machine will be apparent from the foregoing. The wire of course extends thru the soap box and die of one of the units; is wound around the drum E of that unit; extends upwardly thru the guide eye H3 and thence over the transfer roller I05 and then around the die box pulley 200 of an adjacent unit, from whence the wire extends into the soap box-die holder of the adjacent unit, etc.

Each unit is provided with a water supply line 2 I0 having a detachable connection at 2i I, shown in Figure 2 of the drawings with the catch basin wall 13 of the unit. A conduit enters into the compartment 15 of the catch basin and is then upturned as shown at 2I3 in Figure 4 of the This conduit discharges water into compartment 60.

The provision of the pocket or sump 00 permits the water to assemble therein and stay warm for a .while after the unit has been stopped. This prevents sweating and the arrangement of the conduit 2I3 admits oi a better cooling effect Irom the inner surface of the block.

From the foregoing it can be seen that an nism are all located in a single case, but the wire drawing units are themselves readily detachable from this case. The arrangement is extremely simple, with all parts readily accessible and admits of a more eflicient operation of the machine, with less time required to repair breakdowns, etc., than in conventional wire drawing machines.
